## What is AB  Resistors?

AB Resistors is a convenient resistor decoder for quickly determining resistance.

The app supports:

- decoding 3- and 4-digit SMD markings;
- designations starting with the letter R, such as 3R3 and 15R0;
- the EIA-96 high-precision resistor standard;
- calculating resistors with 4 and 5 color bands;
- displaying the value in ohms;
- determining color band tolerance.

Simply enter the SMD resistor marking or select the band colors, and the app will instantly calculate the resistance.

AB Resistors is suitable for radio enthusiasts, engineers, electronics repair technicians, and anyone who works with electronic components.

The app works without registration or internet connection.
